Aim: The aim of this systematic review is to determine the success rate of newer pulpectomy materials for deciduous teeth. Materials and Method: Systematic review of dental literature. Searches of PubMed database were performed using various combinations like “pulpectomy”, “Primary teeth”, “zinc oxide eugenol”, “root canal filling”, “calcium hydroxide”, “iodoform”, “endodontic treatment”, “deciduous teeth”, “necrosis”, “pulp therapy”. 800 articles were found and eventually 7 articles were selected. Result: In the Clinical trials of the 7 main articles, 376 teeth were treated of children aged 2 years 6 months to 9 years and followed up from 3-24 months. We found that 2 articles showed a higher success rate for METAPLEX when compared to ZOE, while in one study we found a similar success rate between the two materials. ENDOFLAS showed 100% success rate when compared to ZOE. ZOE when compared to Calen showed a higher success rate. Conclusion: There seems to be a moderate level of evidence to support the use of both ZOE and iodoform paste with calcium hydroxide as root canal filling materials for deciduous teeth. High quality clinical trials with at least 12 months of follow up are necessary before a reliable conclusion can be drawn as to the best root canal filling material for endodontically treated deciduous teeth.
